Hi Daniel,
Orbit Behavior is designed to move the ViewingPlatform around a
center of rotation while always looking at the center of rotation. So it
won't help you with a Fly behavior, however....
The J3dFly demo application we are about to ship includes some extra
behaviors ( Fly, Hover and Drive ) which extend the ViewPlatformBehavior
class. J3dFly also provides an extensible collision detection system for
the viewing platform.
All these behaviors currently use the Mouse to manipulate the view. This can
be changed by either subclassing the Behaviors and changing the wakeup
criteria and the event processing methods, or writing a KeyListener that
transforms the KeyEvents into MouseEvents and posts them to the Canvas3D.
J3dFly should be available in both binary and source form within a couple of
weeks. I'll post to the alias as soon as the code becomes available.
On a final note, the OrbitBehavior in the beta2 has been updated to
to simplify the API.
